The gas and dust disk around the CQ Tau pre-main sequence star

Young planets are expected to imprint signatures of their formation, such as cavities,
gaps or asymmetries, which are observable in the scattered light and thermal dust
emission in disks. Transitional disks (TDs) are a particularly interesting class of
protoplanetary disks , where the inner regions present a cavity, possibly cleared out
by massive planets. In this project we have studied the dust and gas
distribution in a TD around the CQ Tau (5Myr, d =163 pc, M = 1.5 Mo) using new
new ALMA (Atacama Large Millimeter Array) observations (PI: L. Pérez and L.
Testi). Our goal is to find the best model’s parameters to describe the high
angular resolution ALMA observations and to constrain the properties (mass and
location) of the planet candidate.
